DOUG K. TROTTER, P.E.
PRINCIPAL ENGINEER
POWER CONSULTING ENGINEERS

AREAS OF SPECIALIZATION

General substation design, contract preparation, materials procurement, control and relay system design, relay calibration and setting, protective device coordination, station cut-in and inspection services.

EXPERIENCE

Mr. Trotter obtained experience in transmission and distribution design while working as a coop student at Southern Engineering Co. He developed a software package that solves for all criteria involved in the mechanical design of distribution power lines. Mr. Trotter has also obtained experience in distribution and transmission field engineering. After taking a full time position at Southern Engineering in 1991, he obtained experience in substation design.

Mr. Trotter is very knowledgeable in relay panel design, relay setting calculations and relay testing and calibration. He has experience with electromechanical relays as well as microprocessor relays and PLC's. Mr. Trotter performs periodic system-wide, setting calculation, and relay testing of all substation relays for a number of clients.

Mr. Trotter is a Principal Engineer at Power Consulting Engineers. He is responsible for the scheduling and preparing of plans, drawings, and specifications for substation projects. He evaluates the bids, determines compliance with the specifications, and makes award recommendations. The finished projects are inspected by Mr. Trotter at on-site Final Inspections. Mr Trotter is very experienced in relay panel design, including microprocessor relays and PLC's.

Grande Dunes 115 - 12.47 kV Substation - Horry E.C.I., Conway, SC
Mr. Trotter is the project manager for the 115 - 12.47/7.2 kV substation and is coordinating the project with Horry E.C.I and Santee Cooper (115 kV supplier). The station will have a circuit switcher on the high side, one 14 MVA transformer and four circuits with bus regulation on the low side. Overcurrent and differential relays will protect the station. The project will include preparing final drawings, writing the contract and specifications, biding the project, awarding the erection contract, performing the final inspection, calibrating all relays, performing functional testing of the protective systems and placing the station in service in October 2000. Mr. Trotter has completed six other Horry ECI stations, ranging in size from 14MVA to 56MVA, since 1991

Santee Electric Cooperative, Inc. - Kingstree, SC
Mr. Trotter evaluated all substation relay settings and made recommendations for modifications. He tested and calibrated all relays in 23 stations while making his recommended changes. He performed functional tests of the existing protection systems and corrected numerous problems that would have resulted in mis-operation or no operation of the relay systems.

Cauthens 69 - 12.47 kV Substations; Lynches River Electric Cooperative, Inc. - Pageland, S.C.
Mr. Trotter was project manager for this 69 - 12.47 kV substation and coordinated the project with Lynches River E.C.I. and Santee Cooper (115 kV supplier). The station has a circuit switcher, one 22.4 MVA transformer and six underground circuits with circuit voltage regulation. Overcurrent and differential relays will protect the station. The project will included preparing final drawings, writing the contract and specifications, biding the project, awarding the erection contract, performing the final inspection, calibrating all relays, performing functional testing of the protective systems and placing the station in service in August 2000.

Slappey Drive 115 kV Switching Station and 115 - 12.47 kV Substation - Georgia Power Company - Atlanta, GA
Mr. Trotter was project engineer for this modification. The project included all control design work for replacing three line protection panels and three carrier panels with three new line panels with microprocessor relays. The project also included the addition of a Koyo DL-105 micro PLC to the existing capacitor bank control scheme. The job involved creating 22 new control drawings, modifying 26 existing control drawings, and making obsolete 19 existing control drawings.

Beaulieu 115 - 12.47 kV Substation, Aiken E.C.I. - Aiken, SC
Mr. Trotter was project manager for this 115 - 13.8/7.97 kV substation for the Beaulieu fiber plant. and coordinated the project with Aiken E.C.I, Beaulieu, Inc. and Santee Cooper (115 kV supplier). The station has a circuit switcher on the high side, one 20 MVA transformer and two underground circuits on the low side. Overcurrent and differential relays protect the station. The station also has capacitors for power factor correction with overcurrent, overvoltage and undervoltage protection. He produced drawings, wrote the contract and specifications, bid the project and awarded the erection contract. He performed the final inspections, calibrated all relays, performed functional testing of the protective systems and placed Pthe station in service in November 1995.
